nervous bunny

A small, vibrating stuffed animal - it has a string, you pull the string, release, and an internal motor vibrates like all git out for 30 seconds. The overall impression is that this little bunny is trembling with anxiety. It's a sick thrill at best.

I got one for my last geek boyfriend. We pronounced it's name in a Ren-like voice, something like "neeehrvus bahnee."
